You can broadcast live from within Facebook's social VR app

To do this, you will access a new virtual tool in Spaces that looks like a tablet. Pick it up, hit the "go live" button, and it will livestream your VR world to your Facebook feed where you friends and family can view it. You can then show off various Spaces experiences like traveling through vacation photos, watching a video together or interacting with fellow VR buddies. The tablet, according to Spaces' head of product management Mike Booth, essentially acts as a "magic mirror" of sorts that gives you a view of what everyone will see when they look at the livestream. Think of it as a virtual camera viewfinder.

As you are livestreaming, your audience can add reactions like the Like thumbs up or a heart symbol just like regular Facebook Live, except that in Spaces, those reactions come flying out of the aforementioned "magic mirror" in the VR world. Also, as your audience leaves comments, you will see them appear as stacks next to the magic mirror. If you want to address one comment in particular, you can "grab" the comment from the stack and make it into a virtual sign. This, Booth says, lets people in the VR world talk back to the audience and respond in a personal way.

The inspiration behind the addition of Live was Messenger Video Calling, a feature in Spaces that lets you call people in the real world and have them see you and your virtual avatar in your virtual world. That, however, was a one-to-one experience. "With Go Live, we can have the same experience with many people at the same time," says Booth.

The team has determined that it would be logistically feasible to launch stations like this. However, it's not just a simple matter of building them -- there are numerous questions to be answered. How many of these stations would you need, and where. Who builds them.
